"A word to the Black Man. … Do not point your nose too high. Do not swell your chest too much. Do not boast too loudly. Do not be puffed up. … You are on no higher plane, deserve no new consideration, and will get none. … No man will think a bit higher of you because your complexion is the same as that of the victor at Reno." – The LA Times, Shortly after Jack Johnson became the heavyweight champion of the world.
My interpretation of this quote: America will always dislike a proud black man and do what they can to humble him. Be proud and don't let ANYONE steal your manhood.
